Garbage Disposal Clunking Noise Diagnostic

To confirm a clunking noise, ensure the unit is not currently running. A clunking sound is characterized by rhythmic, heavy metallic impacts occurring within the grind chamber or at the mounting assembly. Verify the symptom by turning the power off at the circuit breaker and manually checking the unit for stability and internal movement. If the unit makes this noise during operation or when manually rotated, the clunking is confirmed.
